NO picture NO sound, chirping 60pp9202


Chirping isnt caused ny the ICs and resistors. The chirping is usually caused by the Flyback ( HV Transformer) or the HOT transistor.

I have a Philips TV Mach3Line 29 inch 29SX8771/75R that wont power up. No Picture, No sound, no power LED, just a high pitched chirp sound every second (not coming from speakers). Is it likely to be worth...


The chirping sound indicates the power supply is starting finding a problem and shutting down hence the cycling trip can be caused by any number of faults but I would first try the Line output transistor for a short collector to chassis if this is ok then Philips TV are prone to the small blue high voltage capacitors (2/3 Kv.102k/222k) becoming short usually indicated by being burnt or very discoloured.. If you are not technically minded its best left to a Tech.. Hope this helps.SUPER8

Same problem as JoshJOhnson posted on Jan 21 08


What is the chassis number on that set. We have a complete Chassis that we are parting out HDTV magnavox with the DPTV 305 through 345 which should be the same chassis as your set. We sell used parts this is a working tv with a cracked blue tube were selling it as a complete chassis or individual boards on our site. Let me know if you may be interested. Chirping comes from the deflection circuits possibly flyback related.

Rainman, can`t really be of any great help on this one, both techs can be right, the chirp is exactly as you thought, the set is trying to come on but there is a short in the set and it`s shutting down because of the short, could be convergence, low voltage power supply, high voltage power supply, until a tech gets in there and starts un-loading circuits it`s impossible to say where the short is, gonna have to call someone out for this one, good luck with it, BMW Rider
